MACHINE FOR CUTTING GROOVES IN DOOR AND WINDOW STILES.

Application filed July 21, 1913.

To all whom it may concern Be it known that I, FRANCIS V. Pnnmtrs,acitizen of the United States, residing at Orlando, in the county ofOrange and State of Florida, have invented new and useful Improvementsin Machines for Cutting Grooves in Door and lVindow Stiles, of which thefollowing'is a. specification.

This invention relates to improvements in machines for cutting groovesin the stiles of door and window frames to receive the headers andsills, the object being to provide an eflicientmachine which will cutthe header groove and an angular sill groove at practically oneoperation for both right and left hand stiles, the machine being alsoprovided with means for trimming the ends of the stiles and for making amiter cut at the header end of the stile when desired.

The machine may also be used for simultaneously cutting. any desirednumber of grooves crosswise of a board, the number being determined bythe number of cutters employed.

The invention consists in the novel fea tures of construction andoperation hereinafter illustrated, described and pointed out in theappended claims.

In the accompanying drawings Figure 1 is a front elevation of a machineembodying my invention. Fi 2 is a top or plan view of said machine. Fig.3 is an end view thereof. Fig. 1 is a cross section taken on line a:m ofFig. 1. Fig. 5 a plan view of a portion of the left hand end of themachine with the work carriage removed. Fig. 6 is a plan view of aportion of the left hand end of the work carriage. Fig. 7 illustrates adoor stile in face and edge view.

In the machine illustrated the main frame consists of a rectangularcasting comprising a front rail 1, a rear rail 2, and connecting endrails 3, said casting constituting the bed of the machine which ismounted upon standards 1 and 5. Slidably mounted upon the front rail 1is a hollow standard 6 forming the support for one end of a cutter shaft7, the opposite end of said shaft being journaled in a standard 8 whichis longitudinally adjustable on the rail 1, and

which is locked in adjusted position by a set screw 9. The slidingstandard. 6 is provided at its base with projecting flanges 10 whichslide in guides 11 secured to the frame rail 1, and is also providedwith Specification of Letters Patent.

spaced bearings 12 for the shaft 7, a driving pulley 13 being mounted onthe shaft between said hearings, as best shown in Figs. 1 and 41.. Theshaft '7 is also provided with fixed collars l l on the outside of thebearings 12 so that the shaft will be moved longitudinally by slidingmovements of the standard 6. The standard 6 is moved by means of a handlever 15, which is pivotally mounted on the frame "ail 1 and connectedto the standard by a link 16.

On the shaft 7 is mounted one or more cutter heads 17 of any approvedtype adapted to cut a groove in a stile properly presented thereto. Onlyone of such cutter heads is shown, but others may be mounted on theshaft 7 when it is desired to cut more than a single lateral groove atright angles to the stile. The cutter 17 is secured to the shaft torotate therewith. For the protection of the operator a guard 18 isadjustably mounted on the frame rail 1, said guard partially housing thecutter and bolted thereto is a support 19 upon which the work rides inpassing over the cutter.

Mounted on the rail 2 of the main f ame is a swiveled standard 20 whichsupports a cutter shaft 21 so that said shaft and cut ter may be turnedto any desired angle with respect to the shaft 7. The standard 20 iscylindrical in form and is provided at its base with an annular flange22 which is housed within a ring 23 secured to the rail 2, as clearlyshown in Fig. 4. The shaft 21 is mounted in spaced bearings 24 formed onsaid standard, and a driving pulley 25 is mounted. on said shaft betweensaid bearings. The shaft 21 carries a cutter head 26, which cuts thesill groove in the stiles, and said shaft may also be provided with acircular saw 27 as illustrated in Fig. 5, for cutting off the end of thestile.

The cutter shafts 7 and 21 are driven from the main driving shaft 28which is mounted in a bearing in the frame standard 41 and having itsinner end iournaled in a bracket 25) bolted to the frame rails 1 and 2.The shaft 28 is provided with a fast pulley 30 to receive a drivingbelt, and is also provided with a loose pulley 31 to which the drivingbelt may be shifted to stop the operation of the machine, as is usual inmachines of this character. A pulley 32 is mounted on the shaft 28, saidpulley operating to drive the cutter shafts by means of a V The belt 33passes under the pulley 32 and over the pulleys 13 and 25 on the cuttershafts and between said last mentioned pulleys the belt passingdownwardly beneath an idle. pulley 34, all as clearly shown in Fig. 4.

A guide 35 is fixedly mounted on the standard 6 above the driving pulley13, said guide consisting of a rail provided with a groove 36 andarranged at a rightangle to the shaft 7. A similar guide 37 is fixedlyiounted on the standard 20, said guide also consisting of a grooved railarranged at a right angle to the shaft 21. These two guides arepivotally connected together, as at 38, midway between the two shafts 7and 21 to form a continuous guide across the two cutter shafts forcontrolling the work holding means, as will be hereinafter described.

It will now be noted that when the standard 6 is moved by the hand lever15, motion will be communicated to the swivel standard 20 through theguide rails 35 and 37 just described, and that the cutter shaft 21 maythus be moved from a position parallel to the cutter shaft 7, as shownin Fig- 5, to a position angular thereto, the direction of movementdepending upon the direction of movement of the standard 6. The limit ofangular movement in either direction is regulated by adjustable stops 39which limit the movement of the standard 6. As hereinbefore described, amovement of the standard 6 carries with it the cutter shaft 7. Theseparts may be locked in adjusted position in any desired manner. Asshown, they are locked in adjusted position by means of the standard 8and its set screw 9, said shaft being secured against longitudinalmovement with respect to said standard by collars 40 as shown in Figs. 1and 2. lVhen an adjustment of the standard 6 is to be made, the setscrew of standard 8 is released to permit said standard 8 to move on theframe rail 1, said standard being thereafter locked in position as willbe read ily understood.

The work carriage is slidably supported upon guide rails 4.1 mountedupon standards 42 at each end of the machine, said rails being providedwith a groove 43 to receive a roller carriage 44, the latter forming aroller support for the work carriage. Said work carriage consists of apair of grooved rails mounted upon a roller carriage 44 at each end ofthe machine, said rails 45 being connected together by beams 46 and 47which are spaced apart sufiiciently to re ceive between them the boardor stile to be operated on.

Mounted on the inner face of the beam 46 is a rock shaft 48 which isslidably mounted in bearings 49. Said shaft carries work supports 50 and51 upon which the board or stile is clamped. Said supports are eachmounted on the shaft 48 between fixed collars, 52 so that any movementof the support 50 to the right or left will be communicated to thesupport 51, the shaft being at all times free to be rocked in itsbearings independently of said work sup ports. The work support 50 isprovided on its under side with a roller 53 which travels in the groove36 of the guides 35 and 37. The support 51 has its free end bentupwardly and over the upper edge of the beam 47 upon which it slides,and said support is also provided with a projection 54 which serves asan abutment or end guide for the work. Said support is adjustable on theshaft to suit requirements by adjusting the collars 52 between whichsaid support is mounted. An adjustable guide 55 is also provided on eachof the work supports 50 and 51 against which the side edge of the workis adjusted.

The work is clamped on the supports50 and 51 by means of clamping arms56 which are fixedly mounted on the shaft 48 and which are provided withadjustable pointed bolts 57 which are pressed into the work by means ofa handle 58 also fixedly mounted on. said shaft.

In Fig. 7 I have illustrated a stile 59 having a straight groove 60 atone end to receive the header of a door or window frame, and having anangular groove 61 at its opposite end to receive the sill. The end ofthe stile adjacent the groove 61 is cut parallel with said groove. Tocut the grooves and angular end of this stile, the standard 6 is movedto the left by means of the hand lever 15. This moves the work guide 37to the angular position indicated by the dotted lines 62, the shaft 21being moved to the angular position indicated by the dotted lines 63.The work support 51 is then adjusted for the length of stile desired,and the cutter head 17 is moved in proper position for cutting thegroove 60. The machine being in operation the board is placed upon thework supports 50 and 51 with one end of the board in contact with theend abutment 54 and its side edges against the guides 55. The clampingarms 56 are then pressed against the work by means of the handle 58, thepointed bolts 57 operating to firmly grasp the work and hold it in position against the work supports 50 and 51. The entire work carriage isnow moved across the machine by means of the handle 58. The work isguided across the groove cutting head 17 for cutting the straight groove60 by means of the guide roller 53 mounted on the under side of the worksupport 50, this roller operating in the slot 36 of the guide 35, thework holding means being thereby held stationary with respect to thecarriage while passing over said cutter. As the carriage advances roller53 enters the slot 36 of the guide 37, and as the latter is in angularposition the work holding means is then moved longitudinally withrespect to the travel of the carriage, the work being thereby presentedto the cutter head 26 to out the angular groove 61, the work travelingacross said cutter in a direction angular to the direction of travel ofthe work carriage. When a saw 27 is employed, this operatessimultaneously with the cutter head 26 to trim the end of the stileangularly as illustrated in Fig. 7. After the work has been passed overboth of the cutters, the operator pulls back on the handle 58. Thisrocks the shaft 458 to release the work clamps, and a continued pull onthe handle draws the carriage back for the next operation. For ejectingthe work from the machine I employ a gravity latch 6t mounted on anextension 65 of the work rest 19. A similar latch 66 is mounted 011 awork rest 67 adjacent to the cutter head 26. Said latches project abovethe work rests, and as the work passes thereover it presses down saidlatches which are thereafter raised by their weighted ends 68 so as toengage the work and prevent its return by carriage, this being a wellknown means for the purpose stated.

Should it be desired to cut a right hand stile, the guide ways 35 and 37are moved to the positions indicated in the dotted lines 69 in Fi 5, theoperation of the machine being precisely the same exceptthat the workholding means is guided in an opposite angular direction over the cutterhead 26 to cut a groove 61 to an angle opposite to that shown in Fig. 7.

It will be readily understood that as many straight grooves as may bedesired may be out crosswise of a board by the employment of additionalcutter heads 17 on the shaft 7 and should no angular grooves be desiredthe guide ways 35 and 37 will be arranged in line with each other asshown in full lines in Fig. 5.

l/Vhen it is desired to miter one end of the board or stile a circularsaw 70 is employed, said saw being mounted upon a standard 71 on theframe rail 2, said standard being adjustable on said rail and beinglocked thereto by a set screw 72. The shaft 73 which supports the saw isjournaled in a yoke 74L which is adjustable with reference to thestandard 71 for permitting the shaft and saw to be moved at any desiredangle as clearly illustrated in Figs. 1 and 2. The shaft 73 is providedwith a driving pulley 7 5, said pulley and shaft being driven by a beltfrom a pulley 7 6 mounted on the shaft 7. Said saw is designed to beused in straight work only, that is, work in which there are no angularcuts to be made by the cutter head 26. The saw 70 may be arranged at anangle of 45 for making a miter cut or may be arranged in an uprightposition for making a straight out, and if the guide ways 35 and 37 bearranged in alinementwith each other, the saw 27 may be used to trim theopposite end of the work as will be readily understood.
